Application f11ed`0ctober 16, 1922. SerialgNo. 594,885.

This invention krelates to receptaclesfor liquids and particularly toreceptacles that` are provided with means for positively dischargingliquidsV therefrom. c

Receptacles have heretofore been provided with means for positivelyejecting they contained liquids, said means comprising av the operatingmechanism of the pump, with the result that said valve has ceased tofunc- Y tion after a relatively short period of use.

Furthermore these types of discharge means have had a very limitedcapacity as regards the quantity of liquid that can be discharged Vat asingle stroke, and have also been expensive to manufacture.

These and other undesirable features have proven by experience to 'be soobjectionable that the sale of receptacles of thischaracter is`decreasing although the demand for a satisfactory receptacle of thistype is increasing.

One of the objects of the .present invention is to provide a receptacleof theabove t-ype which has a positively actuated intak valve. 1

Another `object of this vinvention 4is to pro.- vide pumping meanscomprising an expansible and collapsible vessel which mayv bereciprocated, whereby, through a portion of its movement., said vesselmoves as a whole as distinguished from the previous practice of havingone end wall of the vessel station'- ary while the other end wall aloneYis movable. I

A further objectof thisv inventionis to provide novel means forattaching. the end walls of the collapsible and expansible vessel to theflexible-side wallthereof,wheijeby the necessity of solder for sealingthis joint is avoided, and the cost of manufacture materially reduced.These and other objects will appear as then-description proceeds. 1

The invention is capable of receiving a variety of mechanicalexpressions, several of which for purposes of illustration are shown inthe accompanying drawings, butit is to be expressly understood thatthedrawings are for purposes of illustration only, and are not to beconstrued as definitive of the limits of the invention, reference ybeinghad to the vappended claims for that purpose.

' Fig. 12 is an elevation, partly in section,

' of another embodiment of the invention, the

lower portions of the receptacle and pumping means being. omitted.

1n the form shown in Fig. 1, wherein is illustrated a receptacle or oilcan of the type known in the art as pump type Oilers used for oilinglarge machinery, shaft bearings, locomotives., etc., the mainbodyportion orshell of thereceptacle, whichV may be of any suitableconstruction, material. size, etc., comprises anfupper portionl fittedand secured to alower portion2 by means of a joint 3, which joint. maybesealed by solder or electric welding. A handle 4 of the usual type isattachedv to these portions in'any suitable manner as'by solder or spotwelding. A ferrule' 5secured to upper pore tion 1 by means of a solderedflange 6 and provided with a threaded cap 7 affords the usual fillingaperture.

Any suitable means affording a discharge opening may be provided inupper portion 1.` 1n the illustrated embodiment, a flanged and threadedmember 8 extends through an opening 9 in portion 1, and is secured in nbonnet 18 is a stuffing gland 2() filled with a` place by means of alock nut 10. A spout 11 of any desired length and provided at the lowerend thereof with a flange 12 is secured to the upper end of member 8 bymeans of theinteriorly-threaded flanged nut 13. Attached in any suitable'manner to the lower end of member 8, and interiorly thereof, is thedischarge pipe 14 which will be more fully described hereinafter. Toensure that oil or other contained liquid will not escape from thereceptacle when the latter is in other than the uprightl position, acheck valve 15 having a seat in the upper end of pipe 14, is preferablymounted within the recess in member 8. A compression spring 16, bearingat one end against member 8 and yat its opposite end against a flangeformed on valve 15, normally maintains the latter in seated position. Inorder that any surplus oil that remains in spout 11 after an oilingoperation may drain back into the receptacle a small hole 17 ispreferably provided in valve 15. The above discharge means need not belocated in the center of portionvl, for if desired it can be placed inany other suitable position.`

In order that thev liquid contained in the receptacle may be positivelydischarged, I have provided the following means: Secured to portion 1 ofthe shell of the receptacle, adjacent the upper end of handle 4, is theinteriorly extending bonnet 18 provided with the flanged portion 19suitably secured to the shell as by solder. In the outer end ofsuitablev packing material 21Yheld in place by the usual packing nut 22.Slidably mounted in bonnet 18 is the shaft 23, carrying on its outer endtheusual thumb but- Y ton 24, and suitably secured at its inner end tothe upper, ire-entrant end wall 25 of an expaiisible and collapsiblemember 26. A. tension spring .27, surrounding shaft 23, preferably hasits upper end screwed onto the lower threaded portion of bonnet 18 andits opposite end screwed onto an enlarged portion 28 of shaft23, saidspring normally maintaining the shaft in such a position that. a collar29 formed on the latter is abutting the lower end of bonnet 18.

The flexible corrugated .member 26 preferably made of resilient metal isprovided with a lower end wall 30, having a flanged portion 31 and anopening 32, said flanged portion extending into a guide piece orabutment member 33 suitably secured to the lower end of discharge pipe14 to provide 4an intake valve. The detailed construction of guide 33 isshown more clearly in Fig. 2 where it will be seen that it comprises asuitable number of widely spaced prongs 34 extending substantially atright'angles from'the base portion 35 to telescopically "receive andguide the reciprocating movement of the flanged portion 31 of end wall30. Tube 14 preferably extends downward to, or near, the bottoni of thereceptacle and has its extremity upturned, and guide 33, carryingleather gasket or washer 36, is suitably held in position on the end ofsaid tube Vas by flanging over the end of pipe 14.

The rigid end walls 25 Vand 30 are-preferably secured to corrugated:member 26 as illustrated in Fig. 3, wherein wall 30 is shown asprovided with a return bend 37 around its outer periphery and flexiblemem- Y saving the cost of solder, which is a' material item, butlikewise the labor involved in applying it. Y

The operation of the above described embodiment of the invention is asfollows:V

The receptacle having been filled with oil or i other liquid through theopening provided in ferrule 5 and it being desired to discharge the oilfrom the container, handle 4vis securely held and by means of thumbpressure against button 24 shaft 23 is forced downwardly carrying withit end wall .25, flexible member 26 and end wall 30.' This movementcontinues until the flanged portion 31 of end wall 30 comes into contactwith leather gasket 36 at which time lthe escape of oil between theflanged portion and the gasket is positively prevented. Up to this timethere has been no material collapse of flexible member 26 but furtherdownward inovcment of the shaftv23 and wall 25 causes member 26 tocollapse owing to the fact'that the wall'30 cannot move furtherdownward. The oil or contained liquid is thus forced into pipe 14 andcheck valve 15 is lifted allowing oil to pass out through thev spout 11.Gil is thus continually ejected from spout 11 until shaft 23 and endwall 25 have been moved downwardly to the point where the lowerv portionof wall 25'contacts with lower end wall 30,' whereupon thumb pressure isrelieved from button 24. Spring 16 immediately seats valve 15 andprevents v oil being redrawn from spout 11 and at the same time spring27 forces shaft 23 upward until collar 29 abuts against thebottom ofbonnet 18. This movement of shaft 23, which results inthe expansion of'member 26, cau-ses'the pressure within the collapsible and expansiblemember to drop below the pressure surrounding it, and the area of endwall 30 parallel to the corrugations of member 26 being purposely madelarger than the areav of the flanged end 31 thereof, said wall will belifted 'away from gasket 36 by thev unbalanced pressure, so that oil canpass 1nV between guide prongs 34 and upward through opening 32, therebyallowing flexible member 26 to expand by virtue of its resilience and tobe refilled with oil drawn from the main reservoir of the receptacle.By. again pressing'thumb button 24 the opcan pass therethrough veryslowly and when pressure is removed from button 24 there is no inrush ofoil followed byair from spout 11 to prevent collapsible and expansiblemember 26 from becoming again filled with oil.

In F ig. 4 there is illustrated another embodiment of the inventive ideain which the receptacle is adapted to be used for the storage of oil,alcohol, turpentine and similar liquids. In the form -sh-owln'thebody'or shell portion 39 of vthis receptacle is closed at its upper en dby wall 40 and its lower end by wall 41, the end walls being secured tothe side walls by means of the seams'f42, 43 in any usual and well knownway.r Upper wall 40 is provided with a filling aperture 44 similar tothat previously described. Projecting through the upper wall 40 at anysuitable point is the exteriorly threaded feri'ule provided with flangeportion 46, the latter being suitably connected to wall 40 by rivets orsolder.. Ferrule 45 is provided with stuffing gland 47 carrying asuitable packing material 48 held in position by nut 49. Extendingthrough ferrule 45 is the slidably mounted discharge pipe 50 vcarryingon its lower threaded endl the cup-shaped member 51 having a bottomflanged lportion 52 attached to the re-entrant wall 53 o f thecollapsible and expansible member 26a in any suitable way as by means ofrivets`54.' Wall 53 is provided with an opening 55 concentric with thepip-e V50 and surrounding said opening there may be provided, ifdesired, an annular corrugation 56 which servesas the seat for a leatherflap valve 57 secured e the lateral wall ofthe cup-shaped piece 51.`Immediately above `valve 57 vand at-j tached to the piece 5l'is aperforated metal guard 58 for a purpose to be hereinafter described. Theconstruction Iof the valve 57 and guard 58 are shown more fully in Figs.7 and 8. The lower end of expansible and collapsible member 26a isclosed by a wall .guide prongs 64 .which terminate at their upperextremities in inwardly projecting arms 65. The construction of thisguide is shown in ydetail in Figs. 9v and 10. In afssembling thisportion of the yStructure which constitutes the intake valve, prongs 64are firstmade straight and then thellange 61 of tubular portion on endwall 59 is insertedtherein and the 'inwardly projecting arms 65 are thenbent over into position so thatV flangev portion 61 cannot thereafter bewithdrawn from saidguide. A gasket 66 of anyy suitable material ismount-ed in the lower portion of guide 63 to serve as a seat against`which flange 61v will contact during the operation of the device.Attached to discharge pipe 50 is a split ring 67 which serves as a stopto limit the upward movement of said pipe. The preferred construction ofthis ring is shown in detail in Figs. 5 and 6 where it will be seen thatanannular groove 68 is formed in the outer surface of pipe 50 and intothis groove is Y sprung ring 67 which, as illustrated, is rectangular incross section, the ends thereof abutting as at 69. Threaded on to theupper end of pipe 50 is a bushing 70 which-carries on its' upper end anL 71. A conical valve 72 provided with a threaded stem 73 and handwheel74 is 4adapted to close the upper end of pipe 50 when engaged withthe seat 75 formed in the upper end of bushing 70. A dischargenozzle 76is threaded into the lateral arm of L 7 1 The operation of thisembodiment of the invention is as follows:

VllVlienit is desired to dischargeliquid from the receptacle, valve 72is moved to the open position as illustrated in Fig. 4 by turning handwheel 74 until the upper surface of .said

valve abuts against the interior surface of L f 7l in which position.lit makes a fluid-tight joint with the inner surface of the L andprevents escape of fluid around the threaded stem 73. Hand wheel 74 isthen pulled upward carrying with it discharge pipe 50, cupshaped member51, wall 53, collapsible and expa'nsible member 26, and lower wall 59until the 4flanged extension 61 of the latter contacts with the arms 65of guide 63, whereupon lower wallf59 ceases to move upwardly.

Wall 53 however iscarried still further upward thereby expandingflexible member 26 until split ring 67 contacts with the4 ferrule 45.During this movement oil or any other conta-ined liquid is drawn intocollapsible member 25a through the openings between f the prongs 64 andthe tubular portion 60 of end wall 59. Also valve 57 is securely seatedagainst corrugation 56 at the commencement of the upward movement ofpipe 50 thereby eliectively sealing opening 55. Hand wheel 74rhavingbeen moved to its extreme limit of upward travel, it is now presseddownward until flanged extension 6l comes in contact with vwasher 66 toprevent further flow of liquid between these elements, whereupon the endwall 59 cannot move downwardly any further. and further pressure on handwheel 74 collapses the flexible member 25a so that the liquid which hasbeen drawn into this member 26, being unable to escape back int-o theinterior or" the receptacle, forces valve 57 olf its seat, and passes upthrough discharge pipe 50 and discharge nozzle 76. Pressure on wheel .74is continued until the lower part ofy the re-entrant wall 53 contactswith wall 59 whereupon wheel 74 is moved in the reverse direction andthe operation repeated.

Guard 58 limits the amount of lift of valve 57 otherwise the lattermight be opened so widely and its closing movement require so much timeas to completely drain pipe 50 of liquid and allow air to enter the tankthrough opening 55. When there is liquid in the pipe 50 and wheel 74l islifted liquid rushes through the perforations in guard 58 andimmediately forces valve 57 back to its seat. VAfter the required amountof liquid has been discharged from the receptacle, conical valve 7 2 isscrewed back onto its seat 75 to insure against any accidental dischargefrom the tank. It will be noted that the construction provided in thisembodiment of the invention is such that discharge nozzle 75 may beturned 'in azimuth 360C" without impairing the operation of the pumpingmeans. Valls 53 and 59 are preferably secured to collapsible member 26abyv means of a. lock seam suchas is illustrated in Fig. 3. A very smallhole may be provided in the center of valve 57 to allow liquid which hasaccumulated in pipe 50 to drain back into the receptacle; however, thisis not essential, and I prefer to omit it.

Experience has shown that when a receptacle is being` filled with liquidfor the first time there is a tendency for air to be trapped in the'space 77 between re-entrant wall 53 and lcollapsible member 26a. Thisspace is reduced to a minimum in the illustrated embodiment by havingwall 53 fit very closely inside of member 26a and usually the smallaccumulation of air in this space is not objectionable. but when thekind of liquid being stored and the nature of service required makes itdesirable to eliminate this air, an extremely small airhole'78may berovided near the top of re-entrant wall 5,3 so that as the tank is beingfilled yair will escape out through this small hole. It will be readilyunderstood that hole 78 is .so small that the' amount of liquid whichcan escape therethrough during the pumping action is negligible.

In Fig. l1 there is illustrated another embodiment showing pumping meanswhich may be employed, wherein the outlet valve as well as the intakevalve is positively open ated.. In this embodiment upper wall 53 of theexpansible and collapsible vessel is provided with a. circular recess 79in which is located a disk valve 80 carried on the lower threaded end ofdischarge pipe .50, said pipe, which is reduced in outside Vdiameternear the lower end thereof as at 8l, being slidably fittedy into anopening 82 in the top of wall 53. The bottom end of pipe 50 is closed asat 83 and any suitable number of openings 84 are provided in the sidewalls thereof Vimmediately above valve 80. Lower wall 59 of thecollapsible and expansible vessel is preferably made re-entrant and thetubular inlet 60, provided with a flanged end 61, extends downwardlybetween the prongs 64C of a guide member such as has heretofore beendescribed. It will be noted that in this embodiment of the invention thedischarge valvek 8O is positively actuated during the pumping operationand is not dependent upon liquid pressure. The construction of lowerwall 59 of the collapsible and fexpansible vessel is such that noappreciable amount of air can collect in said vessel when the receptacleis being filled and any air that may collect therein will be quicklydischarged during the first Stroke of the pump.

In Fig. 12 is shown a still further embodiment of the inventive ideawherein the gland 47, packing 48 and nut 49 `of Fig. 4 (or thecorresponding elements of Fig. l) are unnecessary in that a collapsibleand 'expansibleY wall is employed to make this fluidtight joint. In ytheform illustrated, the upper rigid wall 86 of a flexible member 85 issecurely held in position in end member e0 by means of the interiorlythreaded nut 87, thus forming a fluid-tight joint. Lower end wall 88 ofmember 85 is provided with a hub or flanged portion 89 through whichpasses pipe 50, said hub being securely fastened to said pipe in anysuitable manner to form a liquid tight joint. It will be noted that thisconstruction does not permit of discharge member 76 being turned 1nazimuth, and7 in order to insure against undue torsional strain onflexible wall v when actuatingv hand wheel 74, guide '90 is provided inwhich nozzle- 76 slides vertically. Guide 90 comprises a U-shaped memberwhich is secured to wall .l0 of the receptacle Vl. In. a"receptaclefforliquids, vthe combinat-ion of a casing, a member reciprocably''.moimtedin said casing, and pumping means f securedto saidmember, saidmeans includ- .embodiment illustrated in Fig. 4l.V v It Will be notedthat the intake member of the various embodiments has been killustratedas having a greater inside diameter than the discharge or outlet pipe.VThis permits liquid to be taken into the collapsible and expansiblevessel very quickly butit. can

he discharged only as fast as pressure is applied, thus giving the rpumpthe quick return stroke feature. It is to be understood however that theintake and outlet members maybe made the same size if desiredy.

While the several embodiments of the in- .vention illustrated on ,thedrawings have been described 4with considerable particularity it is tobe expressly understood that the invention :is not 4.to be restricted tothe forms there shown since it is capableof` receiving a` Avariety ofmechanical expressions -soiiie of. which Will now readily Y sug estthemselves to those skilled in the art, Wille certain features thereofare `capableof use without. other features thereof. `-Reference istherefore to'be -had to the claims .hereto appended for a deiinitionofthe invention.
